When the phone comes in, the hotel switchboard is always busy.

The switchboard always occupies this number for the following reasons:

1. When the other party is on the phone, you will receive this prompt when you call the other party's mobile phone.

2, the other party is not convenient to answer the phone, hang up directly or not, you will receive the same prompt.

3. When the line is busy, the called party can reconnect after hanging up. The default call mode for all calls is one to one. When the call is established, it means that the caller and the called party are connected, and others are temporarily unable to connect their lines, which means that the line is busy.
